A departmental store offers a wide range of articles under one roof. Therefore, a customer can purchase all his requirements from a particular place. As a result, the time and labour of customers are saved because they need not go from shop to shop for purchasing different kinds of goods.Departmental stores generally purchase in bulk quantities. For that, they receive discounts and commissions. Such stores purchase directly from the manufacturer and hence avoid middlemen and so also their commission.

Departmental store also offers a number of facilities and services like free home delivery, credit, telephone orders, liberal exchange, etc. with courtesy and fair treatment. The availability of such services acts as a special attraction to customers.
